Document Summary
3 joints to consider: hip knee, ankle. The hip: articulation between the head of the proximal femur and the acetabulum of the pelvis acetabulum is a deep socket that provides a great amount of bony constraint joint possesses a large rom in all 3 planes. Hip ligaments: holding the femoral head in the acetabular socket are some large ligaments: ligamentum teres: within the socket itself acetabular labrum: surrounding the socket to make it deeper. Outside the socket are the iliofemoral (y) ligament and the pubofemoral ligament on the anterior side. Outside the socket is the ischiofemoral ligament on the posterior side. In addition to the body and ligamentous constraints, several muscles act to stabilize the femoral head within the acetabulum. These muscles have a large component toward the hip joint centre. During walking gait, when you only have 1 foot on the ground, the pelvis wants to tilt toward your (cid:858)swinging(cid:859) leg.
